3 Product overview
3.1 Area of application/Notes on use
The fans / motors are not ready-for-use products, but conceived as components for
ventilation systems (type designation see rating plate).
The fans may not be operated until they are installed in line with their intended use. The
supplied and certified guard grille of ZIEHL-ABEGG SE fans is designed in accordance
with DIN EN ISO 13857 Table 4 (from the age of 14 up). In the event of deviations,
further structural protective measures must be taken for safe operation.
•Any use below -10 °C is dependent on not being subjected to unusual, sudden or
mechanical loads or stresses on the material (see minimal permissible ambient
temperature).
•Corrosion is possible at the cutting edges on sendzimir galvanised parts.
Attention!
If the motor/fan is used in applications where a ignitable atmosphere can form in the
event of a fault, e.g. due to leakage, the user must assess the risks of ignition and take
appropriate precautions to prevent ignition.
3.2 Functional description
ECblue stands for EC fans and motors with maximum efficiency. Highly efficient, elec-
tronically commutated motors with permanent magnets are used the speed of which is
controlled by the integrated controller.

3.3 Temperature management
The service life of devices with power electronics is decisively dependent on the ambient
temperatures. The longer electronic components are exposed to high ambient temper-
atures, the faster the deterioration and the more probable the failures.
The power electronics protects itself against excessive temperatures by active temper-
ature management (power reduction).
However, this cannot provide complete protection in all circumstances. Observe the
rated data - particularly the maximum permitted ambient temperature - on the rating
plate.
3.4 Note on the ErP directive
ZIEHL-ABEGG SE wishes to point out that, based on the directive (EU) no. 327/2011 of
the Commission of 30th of March 2011 for enforcing directive 2009/125/EC (hereinafter
referred to as ErP directive), the operational area of certain fans within the EU is bound
by certain prerequisites.
The fan may only be used within the EU when it meets the requirements of the ErP
directive.
If the said fan does not have a CE mark (cf. especially the rating plate), use of this
product within the EU is not admissible.
All ErP-relevant information comprises measurements which are determined using a
standardised measurement set-up. More details can be obtained from the manufacturer.
Further information about the ErP directive (Energy related Products-Directive) can be
found on www.ziehl-abegg.de search key: "ErP".

Before the first switch-on, remove any items that may be present (drilling chips,
screws and other foreign objects) from the intake area - risk of injury from any objects
that may fly out!
•For fans, the alignment must be adhered to during operation, e.g. if this is indicated by
“Oben/Top”.
WARNING
Parts of the rotor or the entire rotor coming loose in case of a fault (e.g.
excessive vibrations)
can result in personal injury and material damage.
"Use guard grilles or suitable design measures for critical applications (e.g. refrigerat-
ing systems with refrigerant subject to the ordinance on hazardous substances).
4.2 Connection cable & junction box
Information
In demanding environments (wet rooms, outdoor installation), connection cables must
have water draining pipe elbows. If using a junction box, install this lower than the motor
to ensure that water cannot penetrate through to the controller housing from the
connection cables.

4.4 Assembly in a humid atmosphere
Information
If the device is not in use for longer periods in a humid atmosphere, it is recommended to
operate the motor/fan for at least 2 hours every month at 80-100 % of maximum speed to
remove any moisture that has penetrated inside.
4.5 Motorheating
A continuous power supply is required for safe operation down to the minimum permitted
ambient temperature (see technical data).
If the motor is not operated with an existing power supply (no setting signal, switch off by
enable), the motor heating switches back on automatically at a controller inside temper-
ature of -19 °C and back off when heated up to -15 °C.
Heating takes place via the motor winding whereby a current is induced which cannot
cause rotation.

and provide with suitable screw locking.
Permissible tightening torques M
A
Thread size M6
Property class 8.8, friction coefcient µges 0.12 9.5 Nm
Screw penetration ≥ 1.5 x d
When using screws with different friction values or strength classes, different tightening
torques may be necessary.
Mounting of centrifugal fans, RZ design
Attachment to motor fan wheel mounting according to device manufacturer's specifica-
tions.
Information
•Pay attention to a sufficient screw-in length in the motor flange.
•An excess screw length of max. 3 mm is permissible.
•Every screwing case is different. The tightening torque adapted to it must be
determined by the appropriate screw tests.
•In the case of a vertical motor axis, the respective lower drain hole must be open.
Ensure that the clearance (gap) “a” see fig. be-
tween the fan impeller and the stationary
housing section is constant. Distortion due to un-
even surface may lead to fan failure.
Attention!
•Avoid structural damage or stress with installation. Flange and mounting bracket must
be fixed flat on a level surface.
•The fan must be securely mounted, with vibration dampers if necessary.
4.6.2 Mounting of centrifugal fans design RG.. / RD..
Fastening depending on housing design on flange or fastening brackets.
Information
An additional bracket is required for fastening to the flange. This is available as an
accessory.

Attention!
•Avoid structural damage or stress with installation. Flange and mounting bracket must
be fixed flat on a level surface.
•Provide screwed connections with suitable screw locking.
4.6.3 Erecting the equipment: Design ER.. / GR.. / WR..
•To avoid the transference of disruptive vibrations, we recommend de-coupling the
entire plug fan to avoid sounds transmitted through solids. (Spring and/or attenuation
units are not a constituent part of the standard scope of delivery). Look at our
catalogue for positioning the decoupling elements or request a dimensions sheet
stating the type designation and Part.-No.
•Erect in the open air only if this is expressly mentioned and confirmed in the ordering
information. There is a risk of damage to the bearings if the fan remains stopped in a
moist environment. Avoid corrosion by suitable protective measures. Roofing is
required.
•In the case of a vertical motor axis, the respective lower drain hole (if available) must
be open.
•The GR design in position “H” (horizontal shaft) should be installed in the preferred
direction. The cable guides should point downwards (angled sideways by approx.
30°). This is indicated by the “OBEN/TOP” warning sign on the device.
•Design ER.. / WR.. is only permissible with horizontal motor shaft.
Attention!
•All contact points must be fixed securely. If the fixing is inadequate there is a risk of the
fan overturning.
•Making your own alterations/conversions on the fan module is unacceptable - safety
risk.

4.7 Mounting the motor
Motors design MK
Fastening to fixed motor flange
(assembly of axial fans / fans of design A, D ..) and
(assembly of radial fans of design RH).
•If the motor is used to drive fan impellers or other components, please note the
maximum permissible speeds of the impeller or the component to be driven.
•The max. permissible mass of the impeller ort he component to be driven must be
inquired from and confirmed in writing by ZIEHL-ABEGG.
•Motors are not balanced as standard, a complete balancing with mounted fan impeller
is necessary. The balancing must be done on the fan impeller. The pertinent regu-
lations must be observed.
Design K (with rotor flange) or D (with offset rotor flange) as a drive for fans:
•During assembly of the fan impellers or other components, no inadmissible force may
be applied to the motor bearing.
•Centre the fan impeller accurately and mount without tension on the rotor flange, the
fan wheel must lie flat.
•Use suitable screws for fastening the fan impeller on the rotor flange and fit as
suitable screw lock.
•Every screwing case must be tested for suitability.
•The permissible area pressing of the rotor flange may never be exceeded (depending
on the contact surface).
•Too great a screw overhang is not permitted and can lead to scraping or blocking of
the rotor on the fixed motor flange.
•Motors are not balanced as standard, a complete balancing with mounted fan impeller
is necessary. The balancing must be done on the fan impeller. The pertinent regu-
lations must be observed.

5.1 Safety precautions
Danger due to electric current
•Work on electric components may only be carried out by trained electricians or by
persons instructed in electricity under the supervision of an electrician in accordance
with electrical engineering regulations.
•The 5 electrical safety rules must be observed!
•It is forbidden to carry out work on electrically live parts! Even after disconnection, the
dc-link is still live. Always wait at least 3 minutes.
•Cover neighbouring electrical equipment during installation work.
•Cable glands made out of metal are not allowed in plastic terminal boxes due to lack
of potential equalisation.
•Other measures may be necessary to achieve safe electrical isolation.
•Connect the motor/fan only to electrical circuits that can be disconnected with an all-
pole isolating switch.
•Operating the device with the housing cover removed is prohibited because
energized, exposed parts are present inside the device. Disregarding this regulation
can lead to severe personal injury.
•The final application must ensure that the fundamental health and safety requirements
are met.
•The device owner is responsible for the EMC of the entire plant according to the
locally applicable standards.
•Electrical equipment must be checked regularly: Loose connections are to be re-
tightened and damaged cables must be replaced immediately.
